Let the number be x If: 2x+60 = 120 Then: x = 30
The measure of D is 120.

Well, if there are twice as many boys as girls in a group of 120 children, that means there are 80 boys and 40 girls. So, there are 40 girls in the group. Math doesn't lie, honey.
Without more information, we cannot determine the measure of d. The relationship between b and a does not provide any information about d.
Since diameter is twice its radius, the radius of this circle would be 60
120 degrees = 2X60....supplemental total = 180
